不同育苗方式对尾巨桉幼林生长的影响
Effects of Different Seedling-nursing Methods on the Growth of Young Eucalyptus.urophylla×E.grandis
摘要
Abstract
The effects of different seedli ng -nursing methods, propagation methods and clones were studied by orthogonal test. It was investigated when the trees were 10-month, 23-month and 25-month old. The analysis of tree growth, analytical wood and wind damage showed that: (1) Different seedling-nursing methods had the biggest effects to tree growth, then propagation methods and clones. The best combination of all treatments was clone DH32-29+mesh bag-ftissue culture seedling. (2) Different seedling-nursing methods had the biggest effects to tree biomass, then propagation methods. Propagation methods had the biggest effects to root biomass, then seedling-nursing methods. The seedling developed by tissue culture had larger potential growth than by cutting. (3) Although the growth of clone DH32-29 was better than clone GL9, but it was significantly weaker than GL9 on wind resistant. So, it should be careful to plant it in typhoon areas. (4) The order of good volume growth of combination of all treatments was clone GL9-mesh bag - tissue culture seedlings, cloneDH32 - 29 - mud bag -cutting seedlings, clone DH32-29 - mesh bag - tissue culture seedlings and clone GL9-mud bag-cutting seedlings.关键词
